Description of Problem: When running same-gnome, you should have a black background behind the default stones when removing stones from the playing grid. Instead you have blocks of white area. If you change the stones to planets or anything else during the game you get the correct background color for the pieces selected. You no longer get the irregular white background until you quit and restart the game. Version-Release number of selected component (if applicable): Milan-re0724.nightly

Things look fine to me with 8.0. From what was said in the Gnome bugzilla, perhaps this is an X problem? Can you reproduce this behavior with 8.0?
Looks fine in FC2
